Window screen hook



A ril 8, 1952 R. s. MOORE WINDOW SCREEN HOOK Filed May 15, 1950 WINDOW FRAME SCREEN FRAME I INVENTOR Fla/MAW 6? MOORE ATTORNEY Patented Apr. 8, 1952 UNITED I STATES PATE f o FicE 1 Claim. 1

This invention relates to a window screen hook. and has for one of its objects the production of a simple and efiicient resilient hook which will fasten a screen frame to a window frame with a spring tension, so as to prevent rattling of the screen frame after it is placed in position upon the window frame.

A further object of this invention is the production of a spring tension hook which may be easily and conveniently operated to securely fasten a window screen frame to a window frame and which will hold the screen under a spring tension relative to the window frame.

Other objects and advantages of the present invention will appear throughout the following specification and claim.

In the drawing:

Figure l is a fragmentary vertical sectional view through a window screen showing the same secured to a window frame by means of the spring tension or resilient hook;

Figure 2 is a fragmentary side elevational view of a window screen illustrating the position of the hook when it is in an inoperative position;

Figure 3 is a front elevational view of the hook detached from a supporting window screen frame; and

Figure 4 is a side elevational view of the hook detached from a supporting window screen frame.

By referring to the drawing, it will be seen that I designates a conventional window screen frame, which is adapted to be supported upon a conventional window frame II. A specially constructed spring tension hook I2 is secured to the inner face I3 of the screen frame III by means of a screw or other suitable fastening means It. This screw I4 passes through an eye I5 at the upper end of the hook I2, and this eye I5 fits flat against the inner face I3 of the screen frame II], as shown in Figures 1 and 2 of the drawing. The eye I5 is connected to an integral depending shank I6 from which extends a laterally and downwardly. inclined portion H. An inwardly and downwardly inclined portion I8 depends from the portion I1 and is inclined inwardly toward the central longitudinal axis of the hook I2. The portions I1 and I8 define a laterally extending V- shaped brace to resist lateral twisting strain upon the eye l5 and to provide a relatively broad abutment area. The portion [8 engages an integral forwardly extending coil I9 which extends longitudinally of the central axis of the hook I2 and at right-angles to the eye I5. The coil I9 terminates in a depending tension achoring arm 20 which is provided at its lower end with an anchoring pin engaging hook portion 2I.

An anchoring pin 22 is secured to the window frame I I preferably at the side thereof, as shown in Figure 1, and is inset at a proper distance from the inner face of the window screen frame I3 which window screen frame abuts the outer face of the window frame II. The tension anchoring arm 20 is adapted to be swung inwardly and away from the screen frame In so that the hook '2I engages the anchoring pin 22 when the screen frame it is secured to the window frame II, thereby securely anchoring the screen under a spring tension upon the window frame I I. This is made possible by the fact that the eye I5 is rigidly anchored upon the inner face of the screen frame I0 and the arm 20 is carried by the free end of the coil I9. The coil I9 is adapted to swing the hook 2I of the arm 20 against the frame III when the hook 2| is released from the anchoring'pin 22.

It should be noted that the angular portions I1 and I8 are arranged in diverging relation and fit fiat against the inner face I3 .of the frame Ill and are offset laterally relative to the longitudinal axis of the hook I2 for aligning the eye I5 with the hook 2I and to resist lateral twisting strain upon the hook I2 by the flat contact with the inner face I3 of the frame I0. It should also be noted that the coil I9 extends in 'a plane at right-angles to the plane of the eye I5 and is in longitudinal alignment with the central axis of the eye [5. The hook 2I also is in alignment with the plane of the coil I9 so as to efficiently fit over the anchoring pin 22 to hold the screen frame It snugly against the window frame II and thereby prevent the screen from rattling when placed in position. As many tension hook fasteners as may be desired may be used to hold the screen frame in position.

Certain detail changes in mechanical construction may be made in the structure of the hook without departing from the spirit of the invention so long as such changes fall within the scope of the appended claim. It should be understood that the hook may be reversed if desired, to engage a pin above the hook, within the scope of the invention.

Having described the invention, what I claim as new is:

A new article of manufacture comprising a tension hook for holding a window screen frame from rattling upon a window frame, said tension hook having an anchoring eye at one end adapted to fit flat against one face of a window screen, an integral depending shank connected to said eye, a laterally extending portion carried by said shank, an inwardly extending portion connected.

3 to said laterally extending portion, thereby definingva laterally extending brace having a relatively broad abutment area to resist lateral twisting strain upon said eye of said hook, the brace extending laterally of the longitudinal axis of said shank, a coil carried by the extremity of said inwardly extending portion and arranged in alignment with the central axis or the anchoring eye in a plane at right angles to the anchoring eye, the coil terminating in an anchoring pin engaging tension arm, and said arm having an inturned pin engaging hook portion at the extremity of the arm and in the same plane as said coil.
